Abstract:In the actual production of silver ingot casting machine, there is a phenomenon that the current of silicon carbide rod power connection belt decreases due to high-temperature oxidation. In serious cases, the connection belt will be broken and need to be maintained and replaced regularly. Through the cause analysis of the burning out of the power connection belt of the casting machine, the main influencing factor is that the copper power connection belt is easy to be oxidized and burned out at high temperature. In view of this, a new high-temperature resistant power supply connecting belt is adopted, and a cooling coating is applied to effectively improve the service life of the connecting belt.
